Maxima Fixed Rings are designed to be the strongest, most durable fixed mount system available. Maxima Fixed rings utilize 4 T-15 Torx style socket cap screws for secure optics mounting. The Maxima Fixed series fit Weaver style cross slot bases and incorporate a Warne square stainless steel recoil control key in both the front and rear rings. This ensures a no slip in positive recoil surface across the entire slot of the base and is capable of withstanding the heaviest of recoil. The Maxima square recoil key also protects against swaging or peening of the base when used on softer or less durable materials. The Maxima Fixed ring band width is also substantially wider which offers more ring to scope clamping area to hold the optics firmly in place. The Maxima Fixed Rings are available in a durable DuPont power coat finish in either gloss or matte black and also an electroless silver nickel finish. Warne Maxima scope rings are designed to fit Warne bases as well as all Weaver cross slot and Mil-Spec Picatinny style bases and rails.
